Third-grader Aven Green has been solving mysteries for a <i>whole month</i>, cracking such cases as <i>The Mystery of the Cranky Mom</i>. But can this perceptive detective solve two cases at the same time? First her teacher's lunch bag disappears. Then Aven's great-grandma's dog goes missing. Fortunately, since Aven was born without arms, all the "arm" cells went to her super-powered brain instead. (That's her theory.) This hilarious chapter book showcases a new side to Dusti Bowling's unforgettable protagonist.
